ABSTRACT

We undertook a review and classification of research on electronic commerce (e-commerce) in developing countries. We analyzed 181 articles published in a broad range of journals covering e-commerce, global information technology, and development issues. The analysis provides a roadmap that not only indicates the current state of e-commerce for development research but also identifies gaps and priorities for future research. This will be of significant value to both academics and practitioners who are working on, or plan to work on, e-commerce in developing countries.  相似文献

This article examines the impact of marketing cooperatives on smallholder commercialization of cereals using detailed household data in rural Ethiopia. We use the strong government role in promoting the establishment of cooperatives to justify the use of propensity score matching to compare households that are cooperative members to similar households in comparable areas without cooperatives. The analysis reveals that although cooperatives obtain higher prices for their members, they are not associated with a significant increase in the overall share of cereal production sold commercially by their members. However, these average results hide considerable heterogeneity across households. In particular, we find that smaller farmers tend to reduce their marketed output as a result of higher prices, whereas the opposite is true for larger farmers.  相似文献

Smallholder farmers in Sub‐Saharan Africa often mitigate production risks through cooperative membership: institutionalized arrangements where they pool resources and collectively manage production and marketing chains. Cooperative membership has a significant advantage: it cushions detrimental effects of external forces, placing a premium on a risk‐seeking attitude (experimenting and innovating), which can yield greater accumulation. However, cooperatives are self‐selective institutions: relatively better‐endowed farmers, who are usually less risk‐avoidant than poorer ones (a consequence of their broader material bases), tend to be overrepresented. These two realities complicate the causal assessment of the relationships between risk attitudes, farmers’ socioeconomic status, and cooperative membership that is essential to comprehend the role of cooperatives in local capital accumulation. To help resolve this thorny analytical problem, an experimental study was carried out in eastern Ethiopia—a risky production environment where cooperatives feature prominently and relatively affluent farmers exist alongside poorer ones. It unveils the working of specific path dependences: poorer cooperative members are less risk seeking than nonmembers, but at an interval much less than that observed for affluent farmers. For development policies, this suggests that a greater payoff can be expected from investing in farmers’ material bases than from further improving cooperative membership.  相似文献

Abstract: In this paper, we address two major questions. First, the question of whether China and India are displacing the African manufacturing export from the third market. Second, whether there is an evidence of shifting comparative advantage from China and India to Africa. We employed a gravity model with a panel data using 13 African exporters of clothing and accessories for the period 1995–2005 to answer the first question. To answer the second question, we used a flying‐geese model and estimated Spearman's rank correlation coefficients on indices of the revealed comparative advantage vectors of the African exporters and China and India for the same period. Both the gravity and flying‐geese models predicted similar outcomes. We found that there is strong evidence that China has been displacing African manufactures from the third market while India has been complementing it in the early years of the study. However, the overall third market impact of China and India has been that of complementarity in the later years of the study period. This result is found to vary across countries. Furthermore, we found evidence of shifting comparative advantage from China and India to Africa as the flying‐geese theory predicts, South Africa being the leading goose followed by Kenya. The major implication of the study is that, in the world where China and India are reshaping the global economic order dynamically, the outcomes of the traditionally received wisdom of trade liberalization and industrialization policies through export promotion may be uncertain and requires strategic thinking.  相似文献

Food-for-work (FFW) as a form of food aid has been criticised for its many disincentive effects. This paper investigates alleged disincentive effects of food-for-work (FFW) on labour supply and agricultural intensification and diversification in one district of Ethiopia, using a ranking exercise and a small survey of farmer opinion. Despite the popularity of FFW as a source of income, careful project design meant that disincentives were largely avoided. In particular, the take-up of FFW was restricted, by a combination of self-targeting and community based administrative rationing; and agricultural intensification and diversification were encouraged directly through extension programmes.  相似文献

Abstract

In this article, we analyze opportunities and constraints for upgrading product quality in the dairy value chain in Ethiopia. Our analysis is based on an integrated understanding of supply chain performance both from producer and from consumer perspectives. We outline as main drivers for quality upgrading: (a) factors that influence producers’ willingness to invest toward intensification by smallholder dairy farmers and cooperatives and (b) factors that induce consumer’s willingness to pay for healthy and nutritious dairy products delivered at specific retail outlets. Since there are large gaps between upstream producers incentives and downstream consumers motives, possibilities for dairy quality upgrading remain fairly limited. Given this market structure, decisive policy support is required for better tailoring producer’s investments with consumer preferences.  相似文献

This article reports results from a framed market experiment conducted to examine whether milk choices are responsive to changes in the nutritional characteristics of milk products. Using a random‐effect Tobit model, we analyzed experimental data collected from 160 participants in urban Ethiopia. It shows that sensory properties play a key role in the acceptance of reduced‐fat milk while the provision of nutrition information has a mixed effect on a price premium. Further, a substantial percentage of participants were found to have a strong preference for whole milk while only 19% of them prefer reduced‐fat milk with 2.8% price premium. The study unveils a heterogeneous preference for the nutritional quality of milk products. Consumers’ health problems and socio‐demographic characteristics influence their preference for the nutritional quality of milk products. The result also shows a nutrition‐taste tradeoff, yet consumers place more value on sensory experience. Contrary to earlier studies, we found that prior belief about milk quality influences how consumers value sensory experience and nutrition information.  相似文献

The level of technology adoption is often characterised as low in Africa. Recent evidence, however, points to the coexistence of substantial heterogeneity across farm households and the lack of a suitable mix of inputs for farmers to take advantage of input complementarities. We use a random coefficients multivariate probit model to quantify the complementarities between agricultural inputs and alternative forms of unobserved heterogeneity effects in modeling farmers' technology adoption decisions. The empirical analysis reveals that, conditional on various types of unobserved heterogeneity effects, farmers' technology adoption decisions exhibit strong complementarity for some inputs. The analysis also reveals substantial unobserved heterogeneity effects. We show that ignoring these behavioural features (unobserved heterogeneity and input complementarity) has important implications in quantifying the effect of some policy interventions that are meant to facilitate technology adoption. In particular, ignoring these features leads to significant overestimation of the effectiveness of extension services.  相似文献
